摘要: 相变储能是一种基于材料相变过程吸/放热而实现能量储存的技术,已广泛应用在工业企业能量回收领域。本文针对目前相变材料储/释能过程中热导率低引起能量传递慢的问题,从优化储能结构和添加导热填料两方面综述了相变材料储能过程强化传热技术。优化储能结构方面,分析了开式结构和闭式结构对相变传热过程的影响;添加导热填料方面,讨论了金属翅片、导热粒子、导热纤维和多孔金属对相变材料储能传热过程的影响。分析认为,管壳结构的热损失小,传热效果好;多孔金属作为导热填料增强导热效果更好,并提出复合强化传热会成为今后相变储能领域研究的重点。

Abstract: Phase change energy storage is a kind of energy storage technology based on material phase transition process to absorb energy.It is widely used in industrial energy recovery field.In this paper, the problem of energy transfer is slowed down in the process of storage/release energy of phase change materials.The heat transfer technology of phase change material energy storage process is summarized from the aspects of optimizing the energy storage structure and adding thermal conductivity.In order to optimize the energy storage structure, the influence of the open structure and the closed structure on the phase change heat transfer process is analyzed.The effects of the metal fins, the heat transfer particles, the heat transfer fibers and the porous metal on the energy conversion of the phase change materials are discussed.It is concluded that the heat loss of the shell structure is small and the heat transfer effect is good.The porous metal is better as the thermal conductive filler, and the composite heat transfer will be the focus of the future research.

Key words: phase change materials, energy storage, thermal conductivity, heat transfer enhancement
